This paper describes efforts to build a supply curve for survival of the northern spotted owl in the wild. A survey of experts and a population dynamics simulation model relate species survival to habitat capacity. Home range studies provide the basis for determining the owl's area requirements. Cataloging land in the range of the owl in terms of suitability for owl habitat and for timber production provides the link between timber harvest and the probability of owl survival. Finally, an econometric model of stumpage and wood products markets predicts welfare impacts of timber harvest reductions. The supply curve relates the probability of northern spotted owl survival to the present value to consumers and producers of foregone timber harvest over time.
